Coarse Concrete/ Rock Texture

Use the two hi-def coarse concrete or rough stone textures (4000x3000 Jpgs) to give a really grungy, messed up look to graphics. I've created two versions for one, one quite harsh and coarse whilst the second is much softer.
In the thumbnail I used the softer texture in the sky and the coarse one in the foreground to create an impasto or encaustic wax effect.
